Desert fever is the uncontrollable sexual urge towards people of the middle eastern descent. It should be noted that not all middle eastern people live in desserts, however some might.
Also not all those under the effects develop an actual fever. But their blood flow and body temperature might rise slightly and they might develop a liking for shawarma and falafel.
